Complete first side as follows:
*** Cont to dec 1 st at armhole edge as before on 2nd row, at the same time dec 1 st at neck edge on next 5 rows. = 14[15 : 17] sts.
Cast off.
Sl center 30[32 : 32] sts onto a st holder.
With RS facing rejoin yarn at neck edge of rem 20[21 : 23] sts and patt to last 3 sts, K3.
Complete second side to correspond with first side from ***.

Currently, I have 70 stitches on my needle and the way I'm reading this is that I'm supposed to knit 3, knit in pattern for 17 stitches and then I'm supposed to turn. Well, at this point do I turn the work and add another ball of yarn? How would I work this. Then to continue further, I'm supposed to decrease one stitch at the armhole edge but it says "as before on 2nd row" but before I was decreasing on the first row. Also (sorry for dragging this one) it says that AT THE SAME TIME I'm supposed to decrease one stitch at the neck edge on the next five row to equal 14 stitches but I'm working with 17 so if I decrease one and then five that leave me with 11 stitches on my needle.

Did I confuse you guys yet? LOL

Any help you could provide on clarifying these questions would be greatly appreciated. This is my first garment and I would really like to finish it properly.
